I'm curious if you're still able to change the nicknames.
But I would like to offer for the Weaville.
I'll give a Level 1 Treecko (male).
Moves:
-Aerial Ace
-Brick Break
-Toxic
-SolarBeam
If that's not good enough, i'll have it hold a MasterBall or something.

EDIT: And for the Mandibuzz, I would like to offer a Level 52 Shiny Deoxys.
